Around the end of June my audio went out, since then my dad has tried to help me with it. We finally gave up and decided to reboot my computer and readd Windows XP. The woman who sold the disk said it would add, or update any hardware. We tried that, but it did not work either. I haven't had time till now to try and figure out the problem. I was able to fix two programs that had a yellow question mark when I was in 'Device Mangager' another one popped up after I fixed the two. I uninstalled it and added it again like 'Troubleshoot' said. Once it added itself again it was under the correct spot, but now it had a yellow exclamation point. I have tried to update it by 'Installing it automatically' and 'Installing from a specific location'.They both have the same result, "The hardware was not installed because the wizard cannot find the necessary hardware." (( the file I'm having problems with is 'SIS 7018 Audio Driver' )) Hopefully I explained it well enough, and if you can help me please reply!
